What is a fever?

Our body is used to being at a temperature of between 35.8ºC and 37.2ºC. Sometimes, this temperature goes up. When it goes above 37.8ºC, we say that we have a fever. Between 37.2ºC and 37.8ºC, we talk of a slight fever.

The temperature of our body can change depending on the time of day. In general, our temperature is higher at night. At our age, perhaps we get more fevers than older people.
